Non-Linear Precoding for G.fast - A Case Revisited
Tomlinson-Harashima precoding (THP) is a popular type of non-linear precoding (NLP) scheme and a practical implementation of the optimum precoding scheme for the vector Dirty Paper channel. Analytical and simulated results are presented to show that zero-forcing THP consistently outperforms linear zero-forcing precoding. As an alternative to THP, Lattice-Reduction aided Zero-Forcing precoding with optimum transmit power allocation is also demonstrated.

Rate Optimization for G.fast
With spectrum optimization, a new degree of freedom is available in vectored G.fast to control data rates according to subscriber demands rather than, e.g., maximizing the sum rate. Different approaches are presented to implement rate optimization in G.fast and use cases are investigated.
